Ingredients
- 1 1/2 cups all-purpose flour
- 1/2 teaspoon baking powder
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
- 1 cup unsalted butter (room temperature)
- 1 cup granulated sugar
- 3 large eggs (room temperature)
- 2 tablespoons lemon zest (from about 2 lemons)
- 1/4 cup fresh lemon juice
- 1/2 cup sour cream or plain yogurt (room temperature)
- 2 tablespoons poppy seeds
- 1 teaspoon vanilla extract
- 1 cup powdered sugar
- 2–3 tablespoons fresh lemon juice
Instructions
- Step 1: Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan, making sure to cover every corner to prevent sticking.
- Step 2: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set this dry mixture aside.
- Step 3: In a large bowl, beat the butter and granulated sugar together for 3 to 4 minutes, until the mixture is pale and fluffy.
- Step 4: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the lemon zest, lemon juice, and vanilla extract.
- Step 5: Add the dry ingredients to the wet ingredients in batches, mixing just until the flour disappears. Gently fold in the sour cream and poppy seeds, taking care not to overmix.
- Step 6: Pour the batter into the prepared loaf pan and smooth the top. Bake for 60 to 70 minutes, or until a toothpick inserted in the center comes out clean. If the top browns too quickly, loosely cover it with foil.
- Step 7: Allow the loaf to rest in the pan for 10 minutes, then turn it out onto a wire rack to cool completely.
- Step 8: To make the glaze, whisk powdered sugar with lemon juice until smooth and pourable. Add the juice gradually to reach the desired consistency.
- Step 9: When the loaf is fully cooled, drizzle the lemon glaze over the top and let it set before slicing and serving.
Tips & Variations
- For an extra zing, add a teaspoon of lemon extract along with the vanilla.
- You can substitute sour cream with plain Greek yogurt for a slightly tangier flavor.
- Try adding a handful of blueberries for a fruity twist.
- If you prefer a denser texture, reduce the baking powder by a quarter teaspoon.
- Make sure all wet ingredients are at room temperature to ensure a smooth batter and even baking.
Storage
Store the lemon poppy seed loaf in an airtight container at room temperature for up to 3 days. For longer storage, wrap it tightly and freeze for up to 3 months. When ready to eat, thaw at room temperature and refresh the glaze if needed. Reheat slices gently in a toaster oven for a warm treat.

FAQs
Can I use lemon juice from a bottle instead of fresh lemons?
Fresh lemon juice is recommended for the best flavor, but bottled lemon juice can be used in a pinch. Just be sure it’s 100% lemon juice without added sugars or preservatives.
What can I use if I don’t have poppy seeds?
If you don’t have poppy seeds, you can omit them or substitute with chia seeds or finely chopped nuts for a bit of texture.

Ingredients
Dry Ingredients
- 1 1/2 cups all-purpose flour
- 1/2 teaspoon baking powder
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
Wet Ingredients
- 1 cup unsalted butter (room temperature)
- 1 cup granulated sugar
- 3 large eggs (room temperature)
- 2 tablespoons lemon zest (from about 2 lemons)
- 1/4 cup fresh lemon juice
- 1/2 cup sour cream or plain yogurt (room temperature)
- 1 teaspoon vanilla extract
Add-ins and Toppings
- 2 tablespoons poppy seeds
- 1 cup powdered sugar
- 2–3 tablespoons fresh lemon juice (for the glaze)
Instructions
- Heat the oven. Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan or a bundt pan, making sure to coat every corner to prevent sticking.
- Whisk the dry ingredients. In a medium bowl, combine the all-purpose flour, baking powder, baking soda, and salt. Mix well and set aside.
- Cream the butter and sugar. In a large bowl, use an electric mixer to beat the room-temperature butter and granulated sugar together for 3 to 4 minutes until the mixture is pale and fluffy. This creates a light texture in the loaf.
- Add the eggs and lemon. Beat in the eggs one at a time, ensuring each is incorporated before adding the next. Stir in the lemon zest, fresh lemon juice, and vanilla extract, blending well to infuse the batter with bright citrus flavor.
- Bring it together. Add the dry ingredients to the wet ingredients in batches, mixing just until the flour is fully combined to avoid overmixing. Gently fold in the sour cream and poppy seeds until evenly distributed throughout the batter.
- Bake. Pour and scrape the batter into the prepared loaf pan, smoothing the top. Bake for 60 to 70 minutes. The loaf is done when a toothpick inserted into the center comes out clean. If the top starts to brown too quickly, tent it loosely with foil to prevent over-browning.
- Cool. Allow the loaf to rest in the pan for 10 minutes after baking, then carefully remove it from the pan and transfer to a wire rack to cool completely.
- Make the glaze. In a small bowl, whisk together the powdered sugar and 2 to 3 tablespoons of fresh lemon juice until smooth and slightly pourable. Add the juice gradually to reach your desired consistency.
- Glaze and serve. Once the loaf has completely cooled, drizzle the lemon glaze on top. Allow the glaze to set before slicing and serving for a perfect finish.
Notes
- Use room temperature ingredients to ensure the batter mixes smoothly and the loaf bakes evenly.
- For a dairy-free alternative, substitute sour cream with coconut yogurt and butter with a plant-based margarine.
- Store any leftovers wrapped tightly at room temperature for up to 3 days or refrigerate for up to a week.
- The glaze can be adjusted to be thicker or thinner by adding more powdered sugar or lemon juice.
- Try adding a teaspoon of poppy seeds to the glaze for extra texture.
